The magnetic moment produced in a substance of `1 gm is 6xx10^(-7) "ampere","metre"^(2)`. If its density is `5 gm//cm^(3)`, then the intensity of magnetisation in `A//m` will beA. `8.3xx10^(6)`B. `3.0`C. `1.2xx10^(-7)`D. `3xx10^(-6)` |

Answer» Correct Answer - B `I=m/V=M/(mass//density)`, given `mass=1 gm=10^(-3) kg`, and density `=5 gm//cm^(3)=(5xx10^(-3)kg)/((10^(-2))m^(3))=5xx10^(3) kg//m^(3)` Hence `I=(6xx10^(-7)xx5xx10^(3))/10^(-3)=3` |
